When the inlet grille 7 is lifted upward and rotated, the air-purifying filters 14, together with the holders 15, can be taken to the position of the opening of the air inlet 6, as illustrated in FIGS. 2 and 4 , because the holders 15 accommodating the air-purifying filters 14 are joined to the inlet grille 7 via the links 17.
  • the storage cases 14A of the air-purifying filters 14 are pivotably supported so as to be rotatable by the main unit 2 via the shaft 16, and the front end of the holders 15 are joined to the inlet grille 7 via the links 17, when the front end of the inlet grille 7 is lifted upward and rotated, the front ends of the holders 15 joined to the front end of the inlet grille 7 via the links 17 are lifted upward about the pivotably supported rear ends thereof, in response to such movement.
  • the air-purifying filters 14 disposed in the air passage 12 inside the main unit 2 can be moved to the position of the opening of the air inlet 6, together with the holders 15.
  • the air-purifying filters 14 joined to the inlet grille 7 and disposed in the air passage 12 inside the main unit 2 can be removed from the holders 15 at that position, by being held at the tabs 14B, for necessary maintenance and replacement.
  • the air-purifying filters 14 are disposed in the air passage 12 formed on the upper front side of the front-side heat exchanger 4A, which is disposed diagonally in the main unit 2 so as to extend from the front side to the upper rear side. Hence, the air-purifying filters 14 do not block the flow of air introduced from the air inlet 6 provided in the top surface of the main unit 2, and thus, a decrease in the amount of introduced indoor air due to the air-purifying filters 14 causing pressure loss at the air inlet 6 can be suppressed.
  • the air-purifying filters 14 are disposed with the holders 15 therebetween and can be attached to or removed from the holders 15 in a state in which they are brought to the position of the opening of the air inlet 6.

  • the serviceability of the air-purifying filters 14 can be maintained and ensured.
  • the present invention is not limited to the invention according to the above-described embodiment, and it may be appropriately modified within the scope of the present disclosure.
  • the present invention is not limited thereto and may of course be equally applied to a separate type air conditioner, in which the indoor unit and the outdoor unit are separated.
  • the pre-filters 9 and the air-purifying filters 14 may be appropriately disposed in the form of a single member or in the form of segments, depending on the width of the unit; they are of course not limited to those made up of two segments.
  • the holders 15 accommodating the air-purifying filters 14 are pivotably supported so as to be rotatable at ends and joined to the inlet grille 7 via the links 17 at the other ends so that the air-purifying filters 14 can be brought to the position of the opening of the air inlet 6
